Implementation of Enterococcus casseliflavus Isolated from Swamp Buffalo’s Cecum to Improve Crude Fiber Digestibility of Beef Cattle

Enterococcus casseliflavus coming from swamp buffalo has known as lignocellulosedegrading strain in in vitro digestibility test. Their in vivo capability to degrade feed fiber to improve beef cattle performance was studied. Fifteen head of beef cattles were used in this study to evaluate effect of adding E. casseliflavus on crude fiber (CF), total digestible nutrien (TDN), feed intake, and average daily gain (ADG) of beef cattles. Cattles were separated into three groups; P0, was fed without E. casseliflavus addition, P1 was fed concentrate treated with E. casseliflavus followed by rice straw, and P2 was fed with rice straw and followed by concentrate and E. casseliflavus. The treatments were replicated with 5 replication which experimental design was completely randomized design (CRD), and the differences of mean of variable were tested with Duncan’s multiple range test (DMRT). Result showed that adding of E. casseliflavus could increase CF fiber digestibility from 21.17% (control) to 32.84% in P1 and 28.90% in P2 treatmens, TDN digestibility from 34% (control) to 38% (P2). Dry matter intake of rice straw elevate from 2.54 kg/head/day (control) to 2.87 kg/head/day, and concentrate from 3.91 kg/head/day to 4.17 kg/head/day. ADG was increase from 0.32 kg/head/day (control) to 0.47 kg/head/day in P1, and 0.50 kg/head/day in P2. Based on several variable founded it conclude that P2 treatment showed better than P1, so that the P2 treatment could be recommended for beef cattle
